Description

Arborvitae traditional Chinese medicine extract, extraction method thereof and application of arborvitae traditional Chinese medicine extract in hair washing and caring products

Technical Field

The invention belongs to the technical field of natural plant extracts, and particularly relates to a thuja traditional Chinese medicine extract, an extraction method thereof and application thereof in hair washing and caring products.

Background

Thuja (Thuja Sutchuenensis) is evergreen arbor of Thuja (Thuja) of Cupressaceae, and is an "activated stone" originated from dinosaur age. Researches show that root, stem and leaf of Thuja contains terpenoids such as thujopside, alpha-pinene, limonene, etc., and the terpenoids have good lipid solubility and small molecule, and have antibacterial, antioxidant, antitumor, blood pressure lowering, anthelmintic, antiinflammatory, diuretic, phlegm eliminating, body building and body strengthening effects. In recent years, artificial planting tests of thuja have been performed and succeeded, providing conditions for research and development of thuja.

Pathological hair loss refers to abnormal or excessive loss of hair for a number of reasons. Currently the most common pathologic alopecia is seborrheic alopecia. Seborrheic alopecia is also called androgenetic alopecia, and progressive alopecia of forehead, temporalis and top begins to appear generally around 20 years old. Both men and women occur, but more commonly male patients. The clinical manifestations of seborrheic alopecia are: the initial stage is often itchy, a large amount of hair falls off when scratching or combing the hair, the hair roots of the fallen hair are short and small, and the hair bulbs disappear; the symptoms of alopecia are slow, can be in stages, are light and heavy, and can lead to sparse hair on the top of the head or two temples and bright scalp after years; greasy and greasy head or detritus, and thin, soft and yellow hair. At present, no report that the traditional Chinese medicine extract containing thuja and a hair washing and caring product thereof are used for preventing and treating alopecia, especially seborrheic alopecia, is found.
